Bourns, a major supplier of electronic components, has launched a new line of precision wirewound resistors designed for high accuracy and long-term stability, aiming to meet the needs of engineers in high-reliability applications.
The Riedon Precision Wirewound Resistor Series offers a resistance range up to 6 megohms with ultra-low tolerances of ±0.005%, and comes in multiple axial, radial, and square package formats with a variety of lead configurations. According to Bourns, the devices employ non-inductive multi-Pi cores and protective encapsulation technology, along with a standard temperature coefficient of ±2 ppm/°C, helping to reduce noise and maintain stability under harsh electrical conditions.
Walter Garcia, Resistive Product Line Manager at Bourns, said the company was seeking to support “demanding applications with products that deliver low TCR, tight tolerances, and strong pulse performance.” He added that the resistors could be customised to exacting customer requirements, offering long-term value for critical designs.
Potential applications include measurement instruments, bridge circuits, load cells, strain gauges, imaging systems, current sensing equipment, and high-frequency circuits. Bourns said all units are 100% acceptance tested and RoHS compliant.
Bourns, headquartered in Riverside, California, supplies sensors, circuit protection devices, magnetic components, microelectronic modules, panel controls, and resistive products to markets spanning automotive, industrial, consumer electronics, communications, medical devices, and audio.
